P&O MPPT Integrated PV Fed 15-Level Multi-Level Inverter

Abstract

The Multi-Level Inverter is an essential device in renewable energy source applications for generating the high synthesized levels of output voltage at required quantity even though with help of low or medium voltage DC sources. Due to running out of non-renewable sources, these Multi-Level Inverters are playing the crucial role in modern DC to AC conversion systems for making renewable energy sources as alternative for non-renewable energy sources. These Multi Level Inverter mainly facing challenging consequences of Total Harmonic Distortions, switching losses and less efficiency, and these consequences has to overcome for developing reliable Multi-Level Inverter. In this paper a 15-Level Multi-Level Inverter topology is designed with renewable energy source application. In this methodology PV with P&O MPPT technique is used to fed the 15-Level Multi-Level Inverter. Due to improvised MPPT technique and pulses to the switches will implies to get smooth output voltage with less harmonic distortions. The switching losses are also less for this topology because of less switches are used, that causes less power losses and makes high overall efficiency. The proposed methodology with 15-Level Multi-Level Inverter is designed, simulated by using MATLAB/Simulink software and compared with existing MLI topologies. The simulation results will justify that the designed Multi-Level Inverter is reliable and efficient.
